Eddie, anyone, Opinions, DRZ400s Jetting.

Recommended Posts

Eddie, enjoy reading your threads. Similar question as others, Stock 2003 DR-Z400S 3X3 is done, 1500 - 2500 feet, temps 70 - 105F very very low humidity most time 0-5-10% Just got my JD jet kit from thumpertalk, what jetting, needle & pilolet with Kientech exteneded fuel screw do you recommend.

Is this correct.

Main 155

Blue needle 4 clip

22.5 piolet

Kientech 2.75

Runs good. Temp is cool today 60F, plug is a little on the whiter side then with stock jetting with 3X3.

left plug is stock jetting & 3X3, right plug is above JD jetting with 3X3.

you could probably pull off a 152.5 or 150 main jet.

possibly red needle clip 4.

other wise if it runs well,leave it alone.

Thanks guys!! Just wanted to make sure it was not too lean. I figure its pretty close right now, and in the summer when the air thins and gets hot it will richin a bit. This forum is really great!! Back in the 80,s we drop our tool box off in a ditch with every thing we needed and did our test & tune. How hard would the bike pull, respons, wheels & quarter mile runs. Summer jetting & winter jetting, two jet sizes back thin could cost a piston when the bikes were jetted for the 105F+ and winnter 35s came around.

Agian much thanks, it,s nice to see I could go lower.
